一、安裝軟件

1. 去https://brew.sh/

2. 在主頁上找到上圖的代碼復制到終端（我直接放下面了 更新日期2023年3月28日）

/bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/HEAD/install.sh)"

3. 會出現以下內容，直接按鍵盤上的RETURN或ENTER按鈕繼續(xù)：

==> 正在檢查 `sudo` 訪問權限（可能需要您的密碼）...

密碼：
==> 該腳本將安裝：

/opt/homebrew/var/homebrew/linked
/opt/homebrew/Cellar
/opt/homebrew/Caskroom
/opt/homebrew/Frameworks按 RETURN/ENTER 繼續(xù)或任何其他鍵中止：

4. 根據網速，可能需要一些時間。

若出現警告，則進入第二部分。（M1芯片一般會警告）

????????HEAD is now at 12e7787eb Merge pull request #15058 from apainintheneck/fix-readall-no-simulate

????????Warning: /opt/homebrew/bin is not in your PATH.

????????? Instructions on how to configure your shell for Homebrew

????????? can be found in the 'Next steps' section below.

????????==> Installation successful!

????????

????????==> Homebrew has enabled anonymous aggregate formulae and cask analytics.

????????Read the analytics documentation (and how to opt-out) here:

????????? https://docs.brew.sh/Analytics

????????No analytics data has been sent yet (nor will any be during this install run).

????????

????????==> Homebrew is run entirely by unpaid volunteers. Please consider donating:

????????? https://github.com/Homebrew/brew#donations

????????

????????==> Next steps:

????????- Run these two commands in your terminal to add Homebrew to your PATH:

????????? ? (echo; echo 'eval "$(/opt/homebrew/bin/brew shellenv)"') >> /Users/wangqian/.zprofile

????????? ? eval "$(/opt/homebrew/bin/brew shellenv)"

????????- Run brew help to get started

翻譯（渣機翻幫助理解）：

（前省略）

警告：/opt/homebrew/bin 不在您的路徑中。
?有關如何為 Homebrew 配置 shell 的說明，
?請參見下面的“后續(xù)步驟”部分。
==> 安裝成功！==> Homebrew 啟用了匿名聚合公式和木桶分析。
在此處閱讀分析文檔（以及如何選擇退出）：https:
?//docs.brew.sh/Analytics
尚未發(fā)送任何分析數據（在此安裝運行期間也不會發(fā)送任何數據）。==> Homebrew 完全由無償志愿者運行。請考慮捐贈： https:
?//github.com/Homebrew/brew#donations==> 后續(xù)步驟：
- 在您的終端中運行這兩個命令以將 Homebrew 添加到您的 PATH 中：
? ?echo 'eval "$(/opt/homebrew/bin/brew shellenv)"' >> /Users/yourname/.zprofile
? ?eval " $(/opt/homebrew/bin/brew shellenv)"
- 運行 brew help 開始
- 更多文檔：
? ?https://docs.brew.sh

二、問題說明及操作：

1.說明：類似于windows系統下的配置環(huán)境變量。

要按照“后續(xù)步驟”并將 Homebrew 添加到?PATH，以便brew從終端的任何位置運行。如果不這樣做，每次運行時都會看到brew：

$ brew install something
zsh：找不到命令：brew

2、操作

粘貼入終端并運行：

echo 'eval "$(/opt/homebrew/bin/brew shellenv)"' >> /Users/<willshowyouruserdirectory>/.zprofile

再粘貼入終端并運行：

eval "$(/opt/homebrew/bin/brew shellenv)"

完成。
